ToQaZZ whom it may concern: V Be it known that I, WILLIAM H. Hoornn, a citizen of the United States, residing at Lynn, in the county of EsseX and State of Massachusetts, have invented certain new anduseful Improvements inMachines for Leveling-the Soles of Boots and Shoes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which use the same V r a The present invention relates to machines for operatingupon boot and shoe soles, and more particularly ,to machines'of th s type which comprisea shoe supporting jackiand a' cooperating sole leveling device relatively movable to progressively apply-the pressure overdifferent portions 'of'the shoe sole.

1' In certain machines of this type, and more particularly in machinesof the typeshown and described in the patentto Plant, No. 958,301, patented May :17, 1910, the shoe supporting jack and sole levelingdevlce are relatively actuated to cause a progressive application of the pressure on the shoesole and at theisame time the line of support of the jack is shifted laterally to causethe-levehn'g device to act efficiently over all portions of the shoe sole in'a transverse direction. This shifting of, the line of support, causes the jack to. oscillate in a lateral direction and unless some means are provided for controlling this oscillatiom'the jack tends to'oscillate through an unduly great are which tends to break'the lasts and destroys the uniformity of the leveling operation; r

The object of the present invention; is to provide certain improvements in a machine of the character described which insure a more accurate and uniform operation upon the shoe sole and which tend to .minimize'the vibration of the shoe supporting jack when the machine is in operation.

With. this object in view, a feature of the" invention c'onsis'tsin the provision in a machine of the class described of means for yieldingly controlling the 'sidewise or lateral swinging movements of the jack when the it appertains to make'and of the jack-.-
